Jones and her band the Dap-Kings had planned to release "Give the People What They Want" on Aug. 6 and were already touring. The singer was forced to miss a few shows recently while looking for a cause of her illness.

The release says that doctors caught the tumor early and that the cancer has not spread. They expect the 57-year-old to make a full recovery.

Jones says she'll stay in touch with fans and keep them updated on her condition.
